brake disc options C4 Picasso

Unread post by RobM »

I am looking at replacing both front and rear discs and pads in the next few months, but.
There appears to be 2 options for the front
FRONT DISC DIAMETER 283 THICKNESS 26
FRONT DISC DIAMETER 304 THICKNESS 28
and 2 for the rear

How do I find out which ones my car needs or is just a matter of choice?

What year is your C4 Picasso? What engine and gearbox are fitted?

Post your VIN here (the forum software will mask it) and someone may be able to check using that.

For example, Autodoc for the Picasso C4 offers 3 different disc sizes for the same model. Therefore, it would be best to find out which discs are currently mounted on the car and look for them.

Must be possible to measure them.

Yep, how I did it:
viewtopic.php?p=860317&hilit=Diameter#p860317

(3 different front diameters listed for my 2016 308. Similarly 2 different diameters for the rear of the 2011 308. Note the Haynes manual for the 2011 car doesn't even lift the diameter that was actually fitted!)
